Here at BumbleBar, we love sesame seeds! That might seem like a no brainer but we really can’t get enough of them. Besides being a great option for a gluten free energy bar, sesame seeds are calcium-rich and help build strong bones. Sesame seeds contain three times as much calcium as an equivalent amount of milk. And studies show that sesamin, a lignan found only in sesame seeds, is a strong antioxidant that fights free radicals and helps with your cholesterol.
